[Elsie]

The saying is “I believe in God; God does not exist.”

I understand.

Everything that has been created; has 'existed'.

There has; or will; come a time when the 'existence' of created things will end.

This explains to me a bit more of the fact of God's statement to Moses:

I am.

[Kolokotronis]

"This explains to me a bit more of the fact of God's statement to Moses: I am." Exactly. the words, "Ο ΩΝ" or "ο ων" which you will see on many icons of Christ and of course in the Septuagint at Exodus 3:14, are the Greek for that.
